Got the 40 series and mounted up with proline trenchers that were tape inside. 6S is overpowered but 4S is great. Have a weird problem under hard acceleration the truck pulls to the right doesn't do it under lighter acceleration. I have gone through the alignment to see if that will fix it but it didn't help. Going to add thicker fluid to the front and rear diffs maybe its spinning one tire faster than he other.
